Search for $D^{0}-\bar{D^0}$ mixing using semileptonic decays at Belle
A search for mixing in the neutral D meson system has been performed using semileptonic D^0 \to K^(*)- e^+ nu decays. Neutral D mesons from D^*+ \to D^0 pi+ decays are used; the flavor at production is tagged by the charge of the slow pion. The measurement is performed using 253 fb^-1 of data record...

| description | A search for mixing in the neutral D meson system has been performed using semileptonic D^0 \to K^(*)- e^+ nu decays. Neutral D mesons from D^*+ \to D^0 pi+ decays are used; the flavor at production is tagged by the charge of the slow pion. The measurement is performed using 253 fb^-1 of data recorded by the Belle detector. From the yield of right-sign and wrong-sign decays arising from non-mixed and mixed events, respectively, we estimate the upper limit of the time-integrated mixing rate to be r_D < 1.0 x 10^-3 at 90 % C.L. |
